Description

[Detailed Description of the Invention] The present invention relates to a safety device in a mechanical parking facility such as a vertical circulation parking device.

Recently, more and more cars are equipped with door mirrors, and it has even been approved to install door mirrors on domestically produced cars.In this case, the door mirror must protrude approximately 100 to 250 mm on one side from the width of the vehicle body. Since then, there have been concerns that troubles such as mirror damage or contact may occur while driving in a garage, and this has created a need to install detection means as part of safety measures.

Therefore, the present invention provides a safety device that prevents troubles by checking the width dimension of the car in the door mirror placed on the cage when the vertical circulation parking system turns lower and upper corners during operation. The gist of this is that several dozen pieces are mounted on an automobile via attachments to an endless link chain that is stretched across a pair of sprocket wheels provided on both sides in the upper and lower directions. A parking device of the type in which the cages are suspended and each cage is vertically cyclically driven by rotating the upper sprocket wheel using a suitable drive mechanism, the parking device being fixed to a side wall of a garage room. Support rods arranged vertically in parallel on the entrance and rear guide stands; a door mirror detection bar having both ends fixed to movable sleeves elastically fitted to these support rods; and any one of the above-mentioned 1 The cage is driven and rotated through a striker attached to one movable sleeve and a limit switch installed outside the guide stand, which is turned on and off by the vertical movement of the door mirror detection bar. Therefore, according to the present invention, since the bar switch means are disposed facing each other within the upper and lower turning range of the cage on which the door mirror car is mounted, the door mirror car is If it is off-centered with respect to the longitudinal axis of the cage, it comes into contact with the door mirror detection bar of the switch means and turns off the limit switch, thereby controlling the vehicle width dimension and stopping the garage operation. By doing so, it is possible to prevent accidents from occurring.

Next, the present invention will be explained in more detail with reference to an embodiment shown in FIGS. 1 to 5.

The vertical circulation parking system, as shown in Figure 1,
Two endless bands, for example, an endless link chain 3, are connected to two pairs of opposing upper and lower sprocket wheels 1 and 2 installed on the entrance side and the back side, and several tens of sprocket wheels are connected through attachments 4. The cages 5 are suspended at equal intervals, and the upper sprocket wheel is rotated by a drive device 11 comprising an electric motor 7, a brake 8, a reduction gear 9, a machine stand 10, etc. arranged on a machine base 6. The cages are configured to be circularly driven in the vertical direction, and in this case, the link chain 3 and the cage 5 are connected to a chain guide 12 and a guide roller 13 to prevent rocking during driving.
It is desirable to install a turntable 14 in front of the entrance to enter and exit the garage by changing the direction of the vehicle.

Further, 15 indicates a control panel base, 16 indicates a take-up frame, and in FIGS. 2 and 3, 17 indicates a control panel base.
18 indicates a cage hanger, and 18 indicates a side wall of the garage room 19, and the bar switch means 20 in the device of the present invention includes an entrance side guide stand 21 fixed to both side walls 18, 18 of the garage room 19, and a rear side wall. Support rods 25 and 26 are arranged vertically in parallel on the guide stand 22, respectively.
The inlet side movable sleeve 2 is elastically fitted into the
7 and a rear movable sleeve 28, both ends of which are fixed and covered with a cushioning material such as rubber or resin, and one of the guide stands (in the illustration, the rear guide stand 22).
limit switch 2 that is turned on and off by vertical movement of the door mirror detection bar installed outside the door mirror;
In this case, the support rods 25 and 26 of both guide stands are located vertically downward on the side of the cage 5, and a door mirror detection bar 2 is located at a distance of, for example, 25 mm from the cage 5.
An inlet side movable sleeve 27 and a back side movable sleeve 28, which are attached at right angles to both ends of the tube 3, are slidably fitted on both support rods, respectively, and a locking plate 29 is provided at one end of these movable sleeves. ,3
0 and other locking plates 31 and 32 provided at the lower ends of both support rods are coil springs 3.
3 and 34 are wrapped.

Note that these coil springs can be installed, for example, by attaching the coil spring 33 as shown in FIG.
One end of the bolt 3 is attached to the lower end of the inlet side support rod 25.
The movable sleeve 2 on the back side is hooked to an adjustment bolt 36 threaded onto the free end of a locking plate 31 screwed at 5, and the other end is hooked to another locking plate 29.
8 is provided with a striker 37 that cooperates with the limit switch 24.

Therefore, the device of the present invention having the above-mentioned configuration is arranged in the vicinity of the conversion point between the vertical circulation and the turning drive of the cage 5 shown in FIG. It is installed corresponding to the A level and the B-B level which is the conversion end point, and in this case, the bar switch means 20 of the device of the present invention is installed on both side walls 18 of the garage room 19,
18 in a symmetrical arrangement, and bar switch means 20', 20' of similar construction, each component having a "dash" symbol, are arranged symmetrically on the intermediate stay 38.

However, in the embodiment shown in FIG.
The limit switches 24, 24, 24', 24' are
In the embodiment shown in FIG.
The limit switch 2 is installed on the side wall 18 of the garage room 19 and outside of the
4 and 24 are installed outside the entrance side guide stand 21, and other limit switches 24' and 2
4' is installed on a bracket 39 on the intermediate stay 38, and the entrance side support rods 25', 25' and the rear side support rods 26', 26' are installed on a common bracket 40, 41 on the intermediate stay, respectively. is set up.

Thus, according to the device of the present invention, in FIG. 5, after the door mirror car 42 has passed through the cage hanger 17 and entered the garage, the door mirror car 42 placed on the cage 5 when turning downward and upward during garage operation. The door mirror 43 contacts the door mirror detection bars 23, 23, 23', 23' of the bar switch means 20, 20, 20', 20', which are set to the regulation width dimension in advance. Garage operation is controlled depending on whether or not there is contact with the bar switch means 20, 20, 2 during normal operation.
0', 20', and on the other hand, if the door mirror wheel 42 is biased to either side with respect to the longitudinal direction of the cage when turning vertically, the detection bars 23, 23, 23' of the bar switch means, 23', the door mirror 43 comes into contact with or comes into contact with the limit switch 24, 24, 24', 24', and the limit switch 24, 24, 24', 24' is turned off, which locks the operation of the parking device using a well-known control means and restricts the position of the vehicle in question. This is to prevent accidents from occurring. Further, since the detection bar by the bar switch means is covered with a cushioning material such as rubber or resin, damage to the vehicle can be prevented.
